Great info Thanks. I'm replacing my upper intake manifold now using your posting as a guide.
Quick question, you said, "Intall the block to intake seals with gastket sealant.",can you clearify that a little more for me? Do you mean put gasket sealer on the top and bottom of the end seals or just where the gasket and seals meet?
The insrtuctions that came with the replacement gasket specifically says do not use any chemical sealants other than the one that comes with the gasket and that'* just to be used where the gaskets meet the end seals, any comments?
